Problems solved by technology

[0002] Copper plating on the surface of steel wire has good electrical conductivity and anti-corrosion performance, and also has good combination and extensibility. It can be widely used in electronic components, signal transmission and decorative materials. The current copper plating process can achieve a bright coating, but the current density Small production efficiency is low, the use of cyanide-containing additives can improve product quality and production efficiency but will pollute the environment

Abstract

The invention discloses a steel wire copper plating process which comprises the following steps: 1, oil removing, namely using a chemical process or sand blasting to remove oil, 2, water washing, 3, activation, 4, oven dry, 5, plasma treatment, 6, pyrophosphate copper plating, namely placing the steel wire which is dried and treated through plasma into solution, wherein temperature of the solution is 40-60 DEG C, the potential of hydrogen (PH) value of the solution is 8-9, and the ampere density of the solution is 2-2.5 A / dm<2>, 7, oven dry, and 8, winding and packaging. The steel wire copper plating process is reasonable and simple, small in pollution caused by the fact cyanide-free copper plating is adopted, suitable for mass production and high in production efficiency.

Description

technical field [0001] The invention belongs to the technical field of steel wire surface fine chemical industry, and in particular relates to a steel wire copper plating process. Background technique [0002] Copper plating on the surface of steel wire has good electrical conductivity and anti-corrosion performance, and also has good combination and extensibility. It can be widely used in electronic components, signal transmission and decorative materials. The current copper plating process can achieve a bright coating, but the current density Small production efficiency is low, and the use of cyanide-containing additives can improve product quality and production efficiency but will pollute the environment. Contents of the invention [0003] The object of the present invention is to provide a steel wire copper plating process with reasonable process, high production efficiency and little pollution. [0004] Technical solution of the present invention is: [0005] A ste...
